At 3000K and 8bar, methane (CH4) reacts with the stoichiometric amount of pure oxygen according to CO + 2 HO. The chemical constants for the following reactions are given (all at 3000K): CH + 2 O 2 H+ O 2 H0 with K(T) = 484.9 1/bar C + 2 H CH with K,(7) 9.685 1/(bar) C+0 CO with K,(7) 15.87 1/bar a) Determine the chemical constant for the overall reaction b) Set-up all equations necessary to determine the mole fraction of CH, in equilibrium. Hint: number of unknowns must equal number of equations.
